If it is, how do (or should) I treat it?

It's on a Valley lemon tree.

Welcome!

Its a lichen. You must be in a high humidity area and that is the shady side of the tree. It won't hurt the tree - I always thought getting lichen growing on your trees was very cool.

Lichens are fascinating and completely harmless. They're said to be an indicator of clean air. Love them.
